Characterization of Formaldehyde Emission and Combustion Properties of Peanut (Arachis Hypogaea) Husk-Based Green Composite Panels for Building Applications

The building sectors are increasingly in need of more wood-based panels. Forests and environments are being destroyed to produce these wood-based panels. The aim of this study is to protect forest assets by recycling peanut (Arachis hypogaea) husk and manufacturing particleboard for green building design. The manufactured composite panels were subjected to combustion and formaldehyde tests. According to the test results, peanut husk reduced the combustion time and increased the combustion temperature. Phenol-formaldehyde adhesive decreased illuminance values and the peanut husk ratio increased the illuminance values. It was understood that, when the peanut husk additive ratio increased, combustion times decreased. Slow-combustion of green building composite panels delays the danger of collapse in case of a fire in a building. The combustion performance of the composite panels can be improved by adding non-combustible materials that do not affect the adhesion performance of the composite panels. When the adhesive type is taken into consideration, it is seen that the FF additive ratio reduces the combustion time. According to the formaldehyde emission test results, 24 hours after the manufacturing process all composite panels met the requirements of the board formaldehyde class E1. These composite panels can be used in green buildings as a sustainable building material. The furniture industry can also use these agro-fiber composite panels as green materials.
